GEORGE L. WITSIL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALFOF HIS RIGHT TO JOHN MUNDELL, JR., OF SAME PLAGE.

HEAT-PROTECTING CAP.

SPECIFICATION formingpart of Letters Patent No. 228,796, dated June 15,1880.

Application filed April 16, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE L. WITSIL, a citizen of the United States,residing in the city and county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Heat-Protecting Caps, which improvement is fully set forth in the followingspecification and accompanying drawings, in which Figure l is aperspective view of the cap embodying my invention. Fig. 2 is a view ofthe same twisted 0r bundled.

Similar letters of-reference indicate corresponding parts in the twofigures.

1 My invention consists of a cap for workmen, ball-players, and othersexposed to the sun and other heat, the same being light, simple, andcheap, and adapted, when wet, to be wrung out without injury, and alsoto be made into a compact bundle, in order to be carried in the pocketor elsewhere.

Referring to the drawings, A represents the cap, which is constructed ofthe top piece or crown, a, and the side rim, 1), connected thereto.

The crown a and rim 1) are each formed of two thicknesses, c c, offabric, preferably of cotton, between which is placed a layer or liningof small pieces, c, of sponge, and the whole is quilted throughout,whereby the sponge does 0 not shift in the crown or settle in the siderim.

The operation is as follows: The cap is thoroughly wet, then wrung out,so as to express the surplus water and applied to the head, thus keepingthe latter cool and preventing 5 injurious action of the sun and otherheat thereon.

The rim b applies a wet surface to the head,

and the space between the head and piece a is kept at a low temperatureby the wet surfaces of the crown and rim. 40

The moisture of the head is absorbed by the fabric 0 c, and furtherabsorbed by the spongelayer 0, and as the latter serves as the holderfor the water, it keeps the fabric 0 c sufficiently moist for allpractical purposes, and Without 5 dripping.

When the cap is not required it maybe twisted or bundled in compactform, as in Fig. 2, and carried in the pocket or elsewhere, and as itassumes this form when the water is being expressed, it will resume itsoriginal form, when spread out, without injury, and afterward drywithout materially losing its shape.

If desired, chin orneck straps or pieces may be attached to the cap forfastening-purposes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The top piece or crown, a, formed of the fabrics 0 c,.with theinterposed layer or lining,

c, of sponge, in combination with the rim b, attached to the crown,substantially as and for the purpose set forth.

2. The heat-protecting cap consisting of the top piece or crown, a,formed of the fabric 0 c and interposed sponge c, and the side rim, 7),formed of thei'abric c c and interposed sponge c, the whole beingquilted and operating substantially as and for the purpose set forth.
